Sarah Palin is also on the list.
I do wonder how they compiled the list. According to Forbes:
When we set out to identify this year's list, we decided it was time to look up and out into the broader culture. Our assessment is based less on traditional titles and roles and more on creative influence and entrepreneurship. These power women have built distinctive companies and brands and championed weighty causes, sometimes through unconventional means; in other cases they have broken through gender barriers.
We divided our power women candidates into four groups: politics, business, media and lifestyle (that is, entertainment, sports and fashion). We ranked the women in each group, and then group against group. Not easy, but that's today's reality: an unpredictable, diverse mash-up of hard power (currencies and constitutions) and dynamic power (audience and audacity).
The only brand that LadyGaga has built up is the her own, and I fail to see which weighty causes she has championed (unless they mean gay rights?).
